An engineering evaluation of psychrometric conditions within the primary tank vapor space and the wall annulus of the twenty-eight double-shell tanks was conducted by the Hanford double-shell tank integrity project. The purpose of the evaluation was to identify conditions which can promote condensation on the primary liner surface and identify tanks whose wall annulus region exceeds recommended relative humidity limits. An engineering evaluation of Psychrometric conditions within the primary tank vapor space and the wall annulus of the twenty-eight DST's was conducted by the Hanford DSTIP. The purpose of the evaluation was to identify conditions which can promote condensation on the primary liner surface and identify tanks where the wall annulus region relative humidity exceeds recommended limits. The evaluations employed computer models of the twenty-eight DST's which modeled the heat and mass transfer mechanisms in the primary tank vapor space and annulus region. An evaluation of potential mitigation through ventilation system operations was also evaluated. The mitigation evaluation was intended to provide only preliminary evaluation of mitigation options. The Vapor Space Corrosion panel cautioned against implementation of quick fixes until the surface chemistry and corrosion mechanisms are better understood.
